Three regular polygons, all with unit sides, share a common vertex and are all coplanar. Each polygon has a different number of sides, and each polygon shares a side with the other two; there are no gaps or overlaps. Find the number of sides for each polygon. There are multiple answers.

i mistakenly wrote that the sum of the interior angles should be 180. of course i meant 360, which my examples satisfy.
